TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

To all whom it may concern: 4

Be it known that 1, Moon FELBEL, a citizen of the United States, and a resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful from the crosswise feed to a lengthwise eed only in a given lengthwise field or portion of the ribbon for the purpose of changing from one color or field to another, and, fourthly, to

provide means for arresting the throw of the vibrator or its actuating means at any redetermined field or color, so as to limit t e impression within a selected predetermined part of the ribbon.

To these and other ends my invention con sists inthe various features of construction, combinations, and arrangements of parts hereinafter more fully explained; and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of a typewriting machine embodying my im rovements. 7 Fig. 2 is a detail side sectiona view showin' the several features of my invention. 3 isa detail sectional plan of the ribbon-vi rator lever and the several sto members with which it cooperates. Fig. 4 1s a front sectional view of the shifting mechanism for the stop devices and showing also in section theactuating-leven. Fig. 5 1s a side sectional detail of a modification, omitting some of the features shown in the previouslynamed views. .Fig. 6 is a top plan view, partly in section, ofthe construction shown i 111 Fig. '5. Fig. 7- is a fragment of an inkin ribbon, showing the path in which it is uti ized. I

In the various views the same arts will be i found designated by the same .c aracters of reference.

As will be noted at Fig. 1, I have shown my invention adapted to a Monarch ty ewriter; but of course it may be used in other styles of visible-writing machines.

1 is the base-frame 2, the key-levers 3, the upright sublevers 4, the type-bars connected by links 5 to the sublevers; 6, a universalbar under the key-levers and pivotall mounted at 7 in the base-frame; 8, a top ate; 9, an arm or bracket dependingthere cm; 10, a ribbon vibrator lever pivoted at 11 in said bracket and carrying at its free forward end a ribbon vibrator'or carrier 12 of usual construction.

The rear free end of the vibrator-lever is connected to the universal bar by a link 13 and an intermediate spring connection, which may be of any suitable construction. In the form shown the link 13 asses through an eye 14 in the lever 10 and 1s headed at its upper end. Within said eye and surrounding the link is a coiled spring 15, the lower end of which is seated at the bottom ofthe eye and the upper end of which bears against the under side of the head of the link or connectingrod, the whole being so arranged that when the universal bar is depressed and the link 13 pulled down the lever 10 will be vibrated through the action of the link upon the spring, the spring being normally of sufficient rigidity to resist com ression during the vibration of the lever; but when said lever is stopped and the universal bar.continues to descend under the force of the key-lever saidspring will then be compressed or will yield tothe desired extent on the principle" more fully described in my previous ate'nt, N0. 674,312,.dated May 14, 1901. uring the vibration of the lever the ribbon-carrier of course moves up and down to raise and lower the ribbon 16 in the usual way. .As

customary, the ribbon is adapted to travel lengthwise through the vibrator and from one spool 17 to another. The means for causing this travelin the Monarch machine are illustrated at Fig. 1 and comprise, essentially, a pair of miter-gears 1.81.19 with appropriate shafts 20 21, respectively, and another pair of miter-gears 22 23, the gear 22 being onthe shaft 21- and the gear 23 being on a transverse shaft 24, which derives its mo? tion from a beveled gear 25, properly connected with a gear on the. shaft:24. (Not,

shown.) The gear 25 is connected with a splring drum 26, which in turn is connected "to t epaper-carriage. (Not shown.) The platen thereof, however, is illustrated diagrammat ically at 27. The beveled gears and shafts 18 19, 20 21, 22 23 are in duplicate, one set at each side of the machine, and the gears 23 are arranged to be shifted with the shaft 24 when it is shifted longitudinally, so that the ribbon-winding devices at either side may be thrown in or out of operation as desired and the ribbon Wound either to the right or to the left considered from the front of the ma chine, there being two spools 17, one at each side of the machine.

Referring more particularly to' Figs. 1 to 4, inclusive, underneath the top plate and mounted in suitable brackets or supports is a shaft 28, bearing at its inner end a beveled gear 29, with which meshes a similar gear at the upper forward end of an inclined shaft 31, likewise mounted in suitable bearings and provided at its lower end with a beveled gear '32, that meshes with a gear 33, supported on the ribbon power-shaft 24. The result of this described arrangement is that when the shaft24 turns the shaft 28 is caused to turn in unison therewith;

. rod 40, which is provided with a fingeriece 41 outside of the framework of the mac line, and-which rod is suitably supported in brackets or bearings to enable it to be pushed and pulled and to communicate these movementsto the sleeve 34 and the devices carried thereby. The sleeve is provided with a slot 42, that embraces a pin 42 on the shaft 28, which construction causes the sleeve and attached. parts to rotate with the shaft and also enables the sleeve and its parts to be slid lon-. gitudinally of the shaft. The purpose of this sliding action will now more clearly appear.

.' It will be observed the inking-ribbon 16 illustrated at Fig. 2) 'is drawn to represent a two-color ribbon, the upper field or half a of which may be supposed to be black and the lower-half 1) red. These two-color ribbons are of necessity quite narrow, and preferably some means should be provided to prevent overthrow of the ribbon when set to print in either of the colors. In my aforesaid patent the stop means shown and described will prevent this overthrow. Such sto s are also provided herein, but they are di erently constructed, arranged, and operated.

The stops 35 and 36 are circular in form and are concentric with the shaft 28. The stop 35 is of greater diameter than the stop 36 and will arrest the ribbon-vibrator lever bon and the stop 36 in conjunction with the lower half I) of the ribbon. As shown in Fig. 3, the stop 36 is set in position to arrest the upward swing of the lever 10 and the sto 35 is out of operative position. The stop-s 'fting mechanism is held in this relationship by, a spring-detent- 43, engaging a notch 44 in the rod 40,- Fig. 4. When'it may be desired to put out of use the sto 36 and use the stop 35-, the rod 40 is pulle outwardly and the stop 35 brought into re ister with the lever 10, at which time the detent will engage a notch 45 in the rod 40 to hold the parts in proper working position. It will be noted that these stops 35 36 rotate during the operation of the writing-keys, andthus present new points for thelever to strike against,

The stop 37 is mounted eccentrical'ly on the shaft 28 and is for the purpose of-enaically. This use of the ribbon maytake ,bling the ribbon to be used crosswise automat place when there are two colors employed or 1 when there is only one color in the ribbon;

' but ordinarily the eccentric stop will be used only with the one-color ribbon. It may also be remarked here that the two sto s 35 36 may be used with the one-color ri bon for utilizing the ribbon in two parallel longitudinal fields.

The eccentric stop 37 turns always. with I the shaft 28, and thus presents different portions of its face to the upper edge of the vibrator-lever 10, these di erent portions being different distances from the center of the shaft 28, and as a consequence the lever'lD will be arrested in its upward throw at different distances from itsnormal or rest position, and on account of this differential throw of the lever the vibrator connected thereto will have a corresponding differential throw. Thus different portions of the ribbon width wise will be successively thrown opposite the printing-point and be struck by the types. When the longest radial ,portion of the eccentric is presented to the lever 10, the lever will have its shortest throw, and when the shortest r adial portion of the eccentric is turned to cooperate with the lever 10 the latter will have its longest throw, the dip or depression of the universal bar bein great enough for this extreme throw of the Tever. If the lever 10 be arrested before making its complete throw, the universal bar and the key-lever may nevertheless continue their movement by reason of the spring or yielding connection between the link 13 and the lever 10.

Whenit may be desired to put the eccentric stop into action, the rod 40 is pushed inwardly until the detent drops into the notch 46. This brings the eccentric in register with the lever 10, and by the cooperation of these two devices the ribbon will be utilized in some such manner as that represented in Fig. 7 by the dotted serpentine line, the means for moving the ribbon lengthwise or from one spool to another operating simultaneously; v

Referring now more particularly to Figs. and 6, I have shown a one-color ribbon and have omitted thestops 35 36, retaining only the rotary eccentricistop which normally remains in register'with the lever 10 and ar-. rests its throwwariably, ashereinb'efore described, the (variable arrest being entirely automatic, as reviously explained.

Preferably t 'egears 29 30 32 33- in both forms remain always in mesh, and in order not to disturb the relationshi of the gears 32. 33 when the shaft 24 is shi ted to reverse the longitudinal feed of the ribbon the gear 33 is provided with a hub 33*, which bears against a bracket 33*, and this hub is slotted at 33 to receive a pin 24, projecting from the shaft 24, said pin carrying around the sleeve andgear 33 with the shaft 34, while enabling the shaft to be shifted longitudinally independently of the gear 33.
